No. Atoms are usually considered as spheres so the top or the bottom of one depends entirely on what direction you are viewing it from.
The protons are at the center of the atom. An atom does not have a top or bottom.
The number of electrons in the atom increase from left to right and then from top to bottom.
The Earth's top and bottom are defined by the North and South poles, respectively. The concept of top and bottom is based on human perception, as Earth is a sphere with no true top or bottom in space.
As I understand it scientists took an educated guess at the Hydrogen Atom and all the rest were extrapolated from there.
The first ionization energy generally decreases from top to bottom in the alkali metal family. This is due to the increase in atomic size and the shielding effect from inner electrons, which makes it easier to remove the outermost electron.
The protons are at the center of the atom. An atom does not have a top or bottom.
As we move from top to bottom, number of shells increases and nuclear attraction decreases. Hence nucleus is not able to attract the element at bottom.
electronegativity represents the size of an atom
It would be 9 on top, 4 on bottom and then Be.
The number of electrons in the atom increase from left to right and then from top to bottom.
it depends on which atom it is but you can figure out the number by looking at the periodic table. for example, sodium Na has an atomic mass of 11 (top no.) and a relative atomic mass of 23 (bottom no.), the top number represents the number of protons (and electrons as they are in equal amount) and the bottom number represent the number of neutrons and protons, so, if you take these away from each other you will be left with the number of neutrons the atom has. hope this helps :)
Numerator on top; denominator on the bottom.
Yes it does have a top and a bottom.
it is on the bottom of your arm
The opposites sides always add up to 7. So: * If 1 is on top, 6 is on the bottom * If 2 is on top, 5 is on the bottom. * If 3 is on top, 4 is on the bottom. * If 4 is on top, 3 is on the bottom * If 5 is on top, 2 is on the bottom. * If 6 is on top, 1 is on the bottom.
the top adds what the bottom adds. the top subtracts what the bottom subtracts. the top divides what the bottom divides. the top multiplies what the bottom multiplies.
